If you mean you want to change the color of an object, you might create buttons which each display a different version of an object. This is called a Show/Hide button. Do a Google search on "InDesign show hide button".
Thank you for your answer! I am very grateful for your help. I have tried the show/hide option and i created four separate buttons with the function of showing and hiding all four colours, in a certain order. However, It was not the most efficient solution as i do not have enough space for four separate buttons on that part of my document. What I wish to do is to change the colour of one button by clicking on it, which is possible one time, but doesnt seem to be possible four times. I would also like to stay on the decided colour and save the document, which also didnt seem possible. Do you know any method that would lead me closer to a solution?
As far as I know, that's the only way in interactive PDF. The PDF specification (controlled by an international standards organization) is pretty old and the interactivity features haven't been augmented for a long time. Plus, these days, there are literally hundreds of PDF readers and most of them don't support interactivity well.
This is possible with multiple buttons and show and hide.
- You would have 4 buttons, each colorized differently.
- Button 2-4 are hidden until triggrered.
- Button 1, when clicked will show Button 2, hide others.
- Button 2, now showing, when clicked will show Button 3, hide others. etc.
- When you are finished setting up buttons, then align them to stack over one another.
If you would like, I can send you an Indesign doc with PDF
